This item about markings on toothpaste tubes is yet another Internet-circulated consumer tip that supposedly provides useful information about a common class of product by revealing data that is available only to those “in the know” who are cognizant of where to look for hidden indicators and how to interpret them. And as is typical of such tips, the claim about what these indicators supposedly reveal is completely wrong.
In addition, here are the meanings behind every color that you may come across:
- Green color stands for a completely natural toothpaste
- Blue color means the toothpaste’s composition is natural in combination with medicines
- Red means natural plus chemicals
- Black color equals all chemicals
As it turns out, these colored stripe has nothing to do with the contents of the paste. They’re not even put there by the toothpaste manufacturer, but by the company responsible for making the tube the paste will eventually fill. The industry term for them is eye mark, color marks or printed marks. Simply put, they are markers for the sensors on the machines that cut and crimp them into individual tubes.
These artifacts are supposed to be read by light beam sensors in order to be typically identified so the high-speed machinery knows where the packaging needs to be folded or cut. All these processes work as a connected unit stream.
